I did not ingore, your post was vague
Other than the British describing there experience when dealing with the IRA I couldn't find anything that says they think our policy is nuts and they use different rules. There were no suicide bombers in there IRA conflicts.
I did find this old article which says;
Tensions also rose among British troops near Basra. They had been instructed to stop vehicles 50 meters from their checkpoint and tell the occupants to leave their cars and walk toward the soldiers.
Soldiers then would check the occupants and their vehicles separately.
"If they start coming toward us, I'll empty 200 rounds in them," said Lance Cpl. Dean Brusby, 24, as he manned a machine gun at a checkpoint on the road to Basra's airport.
Do you have a link?
